I recently installed Xubuntu 12.04 (64 bit), coming from Ubuntu 10.04 (64 bit). I did a fresh install, no upgrade. When using Ubuntu 10.04 I had no issues with suspend/resume when closing the laptop lid.
Since being upgraded to Xubuntu 12.04 Suspend/resume sometimes works, sometimes it does not work.
When it does not work it is most often that 'wake up' / resume that fails however sometimes it is also suspend that fails (power light stays on and does not start flashing).
When suspend/resume does not work the screen stays black when I open the laptop lid and I don't get password prompt. Pressing keys, pressing power button does not help. The only thing I can do in that case is holding power button till laptop powers down and I have to restart.
Attached you can find 4 files:
suspend_fails_syslog.txt: Part of syslog that shows log in case suspend fails.
suspend_fails_pm-suspend.txt: Part of pm-suspend log that shows log in case suspend fails
resume-failed_syslog.txt.gz: Part of syslog that shows log in case resume fails.
resume-failed_pm-suspend.txt: Part of pm-suspend log that shows log in case resume fails.
Thanks in advance for giving your time!
